Title: Carbon resistor on alumina ceramic support - pyrolytically deposited on intermediate layer contg. metal or silicon
Inventor: OTTO GERHARD DIPL-PHYS DR
IPC: H01C17/20
Filed: 1973-07-02
Abstract: Resistor consisting of an aluminium oxidoe ceramic support carrying a pyrolytically deposited carbon layer is improved by preliminarily forming on the support a partly oxidised metal (Me) layer, such that gps. Al-O-Me-C- or Al-O-Si-C- are formed then the carbon layer is deposited conventionally. Specif. metal (Me) can be deposited from the vapour phase or by cathodi sputtering.

Title: Drying-unit for freshly printed sheets - has the sheets passing through the unit on an overhead conveyor
Inventor: MATTLE HERBERT
IPC: B41F23/04
Filed: 1973-07-23
Abstract: The sheets emerging from the printing machine are transferred via a turning drum to the delivery gripper which is linked to a chain by parallel arms. Each sheet is drawn against the slide rails by vacuum intake air which prevents flapping of the sheet ends. The rolers of the delivery gripper are deflected on a curve in the direction of the overhead conveyer grippers. The sheet end which moves along the slide rails is held fast by the suction rod which is fixed to the chain. These rods can be adjusted vertically relative to the sheet lengths. Warm air is blown from above onto the suspended sheets. The air stream moves in a direction opposed to that of sheet movement.

Title: Dish-washer with sound-dampening means - has crockery baskets with baffle-type side walls minimizing impact of spray jets on wash container walls
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: A47L15/50
Filed: 1973-09-20
Abstract: The dishwater comprises a housing with a wash container enclosing the crockery baskets or trays whose side walls act as baffle plates to stop the spray jets from the spray devices striking the inner walls of the wash container, which would cause excessive noise. These baffle plates may be plastic or sheet steel, or made from a fine plastics or metal mesh in which case they dampen the effect of the spray against the side walls of the wash container. An improved cleaning effect and reduction in the operating noise is obtained if the side baffle walls of the crockery baskets are at an obtuse angle to the basket base so that the jets directed to the wash container are kept away from the inner wall of the latter and supplied into the baskets.

IPC: A01D46/22
Filed: 1973-11-28
Abstract: A lifting shackle for wine barrels has a mechanically operated double bolt for the lifting lug stud on the barrel, together with remotely controlled pneumatic assemblies for releasing the shackle when the bolt levers are relieved of the weight of the load. The shackle housing has a slot in its front wall, slightly larger than the dia. of the lifting stud, and bell-mouthed below, and pivoting lever(s) is/are arranged in the housing. The load on the stud presses the two arms together and extensions on the levers come into contact at the limit of their inward movement with a stop block. The pivoting points of the levers are placed so that they can swing clear of the slot and are brought back in their unloaded condition by springs to their normal posn. under the stud on the barrel lug. Device is positive in action, accurately adjustable, remote controlled, released without side movement and applicable under very cramped conditions.

Title: Flywheel with overspeed safeguard - has shrink fit on tapered shaft and ball or roller coupling for accelerations
Inventor: HINTERGRAEBER MAX DIPL ING DR
IPC: F16F15/315
Filed: 1974-02-06
Abstract: The hub of the flywheel has a shrink fit on the tapered end of a vertical motor shaft. When the shrink fit is released due to high centrifugal forces the flywheel will drop. Light alloy pads which are mounted on a ring underneath the flywheel support the flywheel while it coasts to a standstill. Sleeves mounted in the end of the flywheel hub will keep the flywheel centralised on cylindrical sections of the motor shaft. When the flywheel is subjected to large accelerations or declerations which would cause the shrink fit to slip, the motor torque is transmitted to the flywheel by means of a coupling. The coupling consists of balls or rollers which are mounted in tapered holes or grooves in a shoulder of the motor shaft and a recess in the end of the flywheel hub.

Abstract: The holder assembly for fastening roofing material on a roof truss assembly may itself be of any desired materials and is formed in a single piece of such a shape and size that, when arranged along the truss it covers it with a thorough sealing and insulating effect and with as much overlap as is desired, while the roofing material can be fixed onto it. The interval between the holder and the roofing material may be filled with foam, and insulating material may be additionally applied, without any additional fixture. Shaped pieces for fixture of storm clamps may be applied, and there may be holes for fixing roof components. Fastening, sealing and insulation are effectively combined in one unit.

Title: Thyristor with increased forward-direction turn-off voltage - has specified abrupt change in doping concentration gradient
Inventor: SCHLANGENOTTO HEINRICH DR RER
IPC: H01L21/00
Filed: 1974-03-27
Abstract: The thyristor has four zones of alternate conduction types as in 2333429 and the doping concentration gradient in the boundary surfaces between two inner zones at first rises gently (in passing outwards from the pn-junctions through the outer regions) and then rises sharply. This graduation of doping concentration alters the properties of the thyristor to give improved 'on' properties so that the maximum turn-off voltage in the forward direction is increased and remains that way. The width of the region in which the concentration gradient changes is specified. The emitter is of p type and there are p and n type bases.
